FIG. 1.

Threshold photoelectron spectrum of CH3Cl in the energy range of 11.0–18.5 eV with a step size of 0.015 eV. The energies pointed by arrows are the dissociation limits, and TPEPICO velocity images of CH3 + are recorded at the energies noted with stars.

FIG. 2.

Energy-selected TPEPICO TOF mass spectra for dissociative photoionization process of CH3Cl. (a) At 11.290 eV (X2E3/2 state of CH3Cl+); (b) at 14.530 eV (A2A1); (c) at 15.480 eV (B2E).

FIG. 3.

TPEPICO velocity image and intensity distributions of CH3 35Cl+(X2E3/2) ions at 11.290 eV. (a) The raw image; (b) intensity distributions along x axis, where black circles are experimental data and red line is the least-square fitting with a Gaussian profile; (c) intensity distributions along y axis.

FIG. 4.

TPEPICO 3D time-sliced images of CH3 + ions and total kinetic energy released distributions from dissociation of CH3Cl+(A2A1) ions at 14.530 eV. (a) The raw image; (b) the modified image; (c) the corresponding total kinetic energy released distributions, where circles are experimental data and the least-square fitting with six Gaussian profiles are shown with solid line.

TPEPICO 3D time-sliced images of CH3 + ions and total kinetic energy released distributions from dissociation of CH3Cl+(B2E) ions at 15.480 eV. (a) The modified image; (b) the corresponding total kinetic energy released distributions, where circles are experimental data and the least-squares fitting with a Maxwell-Boltzmann profile are shown with solid line.

Image of FIG. 6.
FIG. 6.

Experimental and fitted angular distributions of CH3 + dissociated from CH3Cl+(B2E) at 15.480 eV, where open circles represent experimental data and solid line is the fitted curve.

Image of FIG. 7.
FIG. 7.

The Cl-loss potential energy curves of the low-lying electronic states of CH3Cl+ ion along the C–Cl bond length, where the calculated curves from Ref. 18 are slightly vertically shifted to match the experimental dissociation limits. The Frank-Condon area is shown with blue pane.
